Insulating a basement/crawlspace


I have an old home with a basement and crawlspace. It is freezing down there and I need to insulate it. What is the best way to do this? It dosn't have to be pretty as the space will never be used for anything but the furnace etc.

Seal along the rim joist This is the space along the perimeter and between/along the floor joists is where 10% of the heat loss occurs. Seal this area with spray foam or Roxul insulation. You cannot use fiber glass since too much moisture transfers here and will destroy the effectiveness of this type of material.

Spray foam, as Bob said, is the best way. http://www.buildingscience.com/docum...n-crawlspaces/

Be safe, Gary

Side question for you. How do I link my computer to all these excellent references stored on your computer?

Bob, lol. I found that one a few months ago and it was written this year! That's really good for an old timer like me.... Since off work, I have time for research and more research, between the honey-do lists.......

Be safe, Gary
